Table 5.
Character loadings and eigenvalues for Principal Components (PC) I–III. The analysis was based on seven morphometric variables of adult Osteocephalus buckleyi, Osteocephalus cabrerai, Osteocephalus cannatellai sp. n., Osteocephalus festae, Osteocephalus germani sp. n., Osteocephalus verruciger and Osteocephalus vilmae sp. n. Bold figures indicate highest loadings.
